T all whom 15mn/,y concern:

Be it known that I, DELVIN D. ViLLiAMs, a citizen of the United States, residing at Greenwood,in the county of Clark and State of Wisconsin, haveinvented certain new and useful Improvements inMowers; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to'which it appertains to make andv use the same.

|The object ofthe invention is to provide a dividing cutter for mowers for use in har- Vvesting grain, clover and the like, which will `ment of the growing crops,

" form andV proportion may be resorted to within the sco-pe ofthe claims without departing from the spirit of theainvention.

In the drawings:

lFigure 1 is a plan view of a portion lof a mower cutter bar having a dividing or upright cutter -embodying the invention applied in the operative position thereto.

Fig. 2 is a transverse'sectional view taken on a plane indicated by the line 2-2 of Fig. 1.

Fig. plane used in connection with the mower shoe to support certain elements of the divider.

Fig. 4L is a sectional view on the plane indicated by the line 5-5 of Fig. 2.

Fig. 5 is a detail sectional view on the plane indicated by the line 6-6 of Fig. 2.

In the illustrated embodiment of the invention, the usual cutter bar of a mowing machine is indicated at 10, having the fingers 11 and the knives or blades 12 for reciprocatory movement relative to the guard fingers, while at the end of the cutter bar is the usual shoe 13 by which the path of the cutter bar is se arated from the uncut portion of the fiel 3 isa sectional` View 'taken on the Specification of Letters Patent.

Application inea May 15, 191s. serial No. 234,698.

Mounted in a suitable guide 14, carrying fingers'15, is a vertically reciprocable cutter bar 16 having the knives 17, and connected with this cutter b-ar is arocker 18 consisting of a bar fulcrumed as at 19 upon` a bracket 4 2.0 carried bythe shoe 13, said bracket being indicated in detail in Fig. 3. A brace 20" also extends between said bracket and the guide k1li, to mutually strengthen orv stiften the parts, while an actuating spring 21 is shown interposed between the brace 20and said rocker bar toyieldingly hold the latter depressed and return it to its normal position after it has been elevated to correspondingly actuate the auxiliary cutter bar 16. The movement of said auxiliary Vcutter bar,

contrary to the tendency of the return spring:

21, is secured in the constructiony illustrated by a reciprocatory cam22carried by and lirmly attached to the main cutter bar and-of tapered form to pass under the rocker 18, asl will lbe apparent by reference to Fig. l of the drawings. Y

As the terminal shoe of the main cutter bar traverses the ground, it will serve to raise the fallen grain or clover and anyl entangled portions thereof as in the ordinary practice, and this will bring said grain or clover into the zoneof operation of the vertical cutter mechanism, so that the material will be cut along a vertical line or in avertical plane represented by the pathof the shoe, and hence in the course of the progressl of the mowing machine, the path traversed thereby `or thejswathcut thereby will beclearly defined ,fori the guidance of the operator of the -machi-ne in making'the next traverse of the field, to avoid going over'- the same ground twice in order to cut and harvest all Vofthe'materi'al, and also to avoid leaving uncut such portions of the crop as ordinarily would not be reached by the main cutter mechanism and hence would be left in a more or less Hat condition upon the field. In order to minimize the friction and hence the power necessary to operate the additional or supplemental cutter mechanism, the rocker bar 18 may be provided with an anti-friction sleeve or roller 23 for contact with the cam carried by the main cutter bar, but owing to the elimination of back draft or resistance due to the entangled grain or clover at the outer end of the main cutter bar, the side draft upon the machine is materially lessened or entirely eliminated, and consequently there is less strain upon the ma- .upper orexposed vside of lthe-cutter bar to project .toward the .terminal shoe of the main cutter mechanism, :and: :the guide :for the auxiliary -fcutter bar and the bracket, shown in Fig. 3,'beirng readily attachabl-e-to' said'shoe without in anyway affecting .the normal operations or functionsiof the main or usual cutter mechanism. Obviously, theauxiliary cutter bar .should lbe arranged sto operate. as near the' vertiicalplane oftheex- '.'terior surface of the shoe' oftthe imain; cutter.

mechanism as possiblabut within the plane thereof sufficiently/to insurea .Wehl defined division betweenithe cut` and uncut portions.

of the field' so `thatithe necessity of .a khelper for the driver or Voperator-'ofv lthe mowing machine, in'ord-er to yclear the way for the machine :and indicate the path ywhich the sames'hould ollow-,onthe succeeding trip or traverse of the eld, may be avoided. fIt will also .be obvious that the attachment may be constructed ,at a small cost relative to the main mower vmachanism, and being made independently ythereof, maybe applied Vto any :ordinary mowing .machine withoutthe, exercise of skilled labor.

Having described the invention, I claim: .1. .In aimachine of the class described, the combination with 'a main cutter bar and terminal 6h08, -ofan .Lipright supplemental cutter-bar, .a bracket carried by' said shoe, a Vrocker Abar fulcrumed upon lthe said bracket and having connection with the supplemental cutter.y barfaspring formoving the :rocker barvin one direction, and a cam Copiesmfthis; patent maybe obtained forvecents each, by,faddres'sing.t1ie icomlinssioner .of latentgs. i
